Abstract

Significant technological advances have occurred on the execution and control of embankments and compacted layers in transportation infrastructure. These advances are particularly relevant to railways since the allowable settlements for the service limit state design are very stringent. This paper reports the advancements in material management, compaction machinery technologies, and quality control devices and processes. Emphasis is placed on the deflection-based and seismic methods that have been automated for these purposes. The strengths and limitations of these methods will be discussed. The results from a number of field trials will be presented to discuss the best use of these methods.
